Pdib, Thanks for posting pictures and for providing the link to your thread. Yea I would agree that it would be foolish to use your mod. Loose metal in a device is not a good idea. BTW, my mod is performing flawlessly with flat tops. While it still early to tell the longevity before oxidation kicks in, I have no issue currently (In fact, I actually pick up a whopping .05v).
I am gonna keep my mod in place until my flawless new AW IMR18650s come in. I aint putting my reo down to wait for the mailman.
